In the drawings, Figure 1 is a side-view of the device, showing the clamp holding the bricks. Fig. arch and walls. Fig.' 3 is a top plan view.

Referring specifically tothe drawings, .10 are two segmental spaced bars of iron or` x are the bricks and x1 are recesses in the upper part of the side wallsfor supporting 1 1 are end plates extending across between the ends of the bars 10, and having lugs 11EL through which a bolt 12 passes, havin ,nuts 12 tohold the.. same.
